where can I get one of these bearings ?
 
 

If you go here, you can find the part number of the bearing you're after. It appears to be 90369-43008.

Once you've confirmed that, you can order it from Amayama. Seems they even have one in stock in Sydney right now.  Just $29.91 plus postage.

Amayama is both reliable and has competitive prices. I've bought parts through them many times.
